6 Factors To Consider When Installing A Tankless Water Heater

When looking to install a tankless water heater at your home or business, it is important to consider a few key factors. Location, energy efficiency, and cost are all important to keep in mind. When it comes to selecting a tankless water heater, Sharpline HVAC in Mississauga is here to help.


Choosing the right location is essential when installing a tankless water heater. Tankless water heaters require access to a gas line, so it is important to ensure that your desired location has access to one. Most tankless water heater models will require a dedicated gas line, as they need a large amount of gas to operate. In addition, tankless water heaters also require access to a vent, as the exhaust gasses need to be vented outside the building.


Energy efficiency is another important factor to consider when selecting a tankless water heater. Tankless water heaters are much more energy efficient than traditional storage tank water heaters, as they only heat the water when it is needed. This results in significant energy savings on your utility bills. Many tankless water heater models are EnergyStar certified.


Finally, it is important to consider the cost of the tankless water heater. Tankless water heaters tend to cost more upfront than traditional storage tank water heaters, but they are much more cost-effective in the long run. They require less energy to operate, resulting in lower energy bills. Additionally, tankless water heaters tend to last much longer than traditional storage tank water heaters, resulting in fewer maintenance and repair costs.

Unit capacity

While sizing a conventional water heater mainly comes down to tank storage capacity, with a tankless there’s a bit more work. Getting the highest capacity might work for you, since the units work in the range of 20,000 BTU to 200,000 BTU. With the highest unit capacity, you also will spend a bit more and a bigger unit. It’s best to consult a local company if unsure.

Tankless water heaters use 3 to 4 times more BTUs than traditional water heaters. This doesn’t mean a tankless uses more gas - it just requires a bigger initial kick to get going since the water isn’t already a heater. Generally, you require a ¾ inch. Ask your local HVAC company to verify whether your current gas line is adequate or if you’ll need to modify it to provide sufficient gas flow to your new unit.

Electrical Power


Even if your tankless water heater runs on gas, its PC board and digital remote require electricity. You’ll need a 120V and because of this, in the event of a power outage, you will lose hot water.

Rental/Owner occupied

If you’re considering a tankless for a rental, and if you’re paying for utility, you might want to think twice before installing a tankless. Since there’s an endless amount of hot water this can raise your utility bill, water bill and your sewer bill for your rental. However, if it’s for your own home, having unlimited hot water might be a luxury you might be willing to spend for your family.
